In place of bakelite I may substitute a material known as hard `ibre, but I recommend bakelite because of its wearing qual- 'ity7 its appearance and because of the actual 5 results obtain-ed.

What I claim and desire to secure by Letters-Patent is A runway for metal trays comprisinga supporting rail substantially rectangular in cross section having an upper corrugated portion adapted `for slidable Contact with the bottom of a tray, and the lower portion of said rail adapted for seating within the slot of et` base rail member, and means in the bottom of said bare rail for adjusting the contained rail relative. thereto.

In testimony whereof I affix my signature.
